access and benefit sharing

Access and benefit-sharing (ABS) refers to the way in which genetic resources may be accessed, and how the benefits that result from their use are shared between the people or countries using the resources (users) and the people or countries that provide them (providers). In some cases, this also includes valuable traditional knowledge associated with genetic resources that comes from Indigenous Peoples and Local Communities. The benefits to be shared can be monetary, such as sharing royalties when the resources are used to create a commercial product, or non-monetary, such as the development of research skills and knowledge.

Global assessment (1st work programme), Sustainable use assessment
access and benefit sharing

One of the three objectives of the Convention on Biological Diversity, as set out in its Article 1, is the fair and equitable sharing of the benefits arising out of the utilization of genetic resources, including by appropriate access to genetic resources and by appropriate transfer of relevant technologies, taking into account all rights over those resources and to technologies, and by appropriate funding. The CBD also has several articles (especially Article 15) regarding international aspects of access to genetic resources.

Americas assessment
acclimatization

A change in functional or morphological traits occurring once or repeatedly (e.g. seasonally) during the lifetime of an individual organism in its natural environment. Through acclimatization the individual maintains performance across a range of environmental conditions. For a clear differentiation between findings in laboratory and field studies, the term acclimation is used in ecophysiology for the respective phenomena when observed in well-defined experimental settings. The term (adaptive) plasticity characterises the generally limited scope of changes in phenotype that an individual can reach through the process of acclimatization.

active restoration

See restoration.

Land degradation and restoration assessment
actor

Individual person or group representative that is involved in a specific decision- making context.

Europe and Central Asia assessment
actor

Actors may be understood as individuals operating certain roles or functions in society.  Hence, the same individual may for instance (i) serve as a political actor, (ii) operate as an economic actor, and (iii) act as a community member/citizen. They may therefore emphasise different goals and values when dealing with particular issues. For this reason, the values assessment uses a typology that includes these actors recognizing the fuzzy relationships that exist among them. See Affected actors, Key players, Influence.

Values assessment
actor

Active stakeholders influencing a policy or decision-making process.

Scenarios and models assessment
adaptability

The capacity to adjust responses to changing external drivers and internal processes, and thereby channel development along the preferred trajectory in what is called a stability domain.

Global assessment (1st work programme)
adaptation response

Responsive outcome from adaptations, either antropogenic (such as adaptations to environmental change) or natural (such as species adaptations, possibly arising from selective pressures).

Asia-Pacific assessment
adaptation

Adjustment in natural or human systems to a new or changing environment, whether through genetic or behavioural change.

Europe and Central Asia assessment, Americas assessment, Asia-Pacific assessment
adaptation

Adjustment in natural or human systems in response to actual or expected stimuli or their effects, which moderates harm or exploits beneficial opportunities.

Sustainable use assessment
adaptive capacity

The general ability of institutions, systems, and individuals to adjust to potential damage, to take advantage of opportunities, or to cope with the consequences.

Land degradation and restoration assessment, Asia-Pacific assessment, Global assessment (1st work programme), Americas assessment, Europe and Central Asia assessment
adaptive capacity

The resilience of an ecological, social or social-ecological system to unexpected or unpredictable shocks.

Sustainable use assessment
adaptive co-management

An extension of Co-management. A means of sustaining socio-ecological systems by building their resilience and adaptive capacity and establishing sustainable pathways as well as providing a novel institutional arrangement to generate adaptive responses.

Asia-Pacific assessment
adaptive management

A formal procedure for learning by doing, that is particularly amenable to sequential decision problems.

Global assessment (1st work programme), Scenarios and models assessment
adaptive management

A systematic process for continually improving management policies and practices by learning from the outcomes of previously employed policies and practices.

Pollination assessment, Europe and Central Asia assessment
agribusiness

Collective business activities that are performed from farm to table. It covers agricultural input suppliers, producers, agroprocessors, distributors, traders, exporters, retailers and consumers. Agro- industry refers to the establishment of linkages between enterprises and supply chains for developing, transforming and distributing specific inputs and products in the agriculture sector. Consequently, agro-industries are a subset of the agribusiness sector. Agribusiness and agro-industry both involve commercialization and value addition of agricultural and post-production enterprises, and the building of linkages among agricultural enterprises. The terms agribusiness and agro-industries are often associated with large-scale farming enterprises or enterprises involved in large-scale food production, processing, distribution and quality control of agricultural products.

Land degradation and restoration assessment
agricultural commodity
